[0030] At present, the installation of external handles 800 for upper cabinet door panels in the furniture industry is generally completed by manual operation. The cut and punched handle 800 is placed at the location where the cabinet door 700 needs to be installed (the side or plane of the door panel), and is manually pressed and fixed while screwing for installation. However, this method has processing deviations. For example, after screwing, the installation gap between the handle 800 and the cabinet door 700 is uneven, and at least two people are required each time to assemble the handle 800 and the cabinet door 700, which has high labor costs and low production efficiency. Therefore, it is urgent to develop an installation device for assisting the fitting of the cabinet door 700 and the handle 800.

[0031] Reference Figure 1 The installation device of the external handle of the cabinet door of the embodiment of the present invention comprises a mounting base 100, a positioning member 300, a first clamping assembly 500 and a second clamping assembly 600. The mounting base 100 is provided with a storage platform 200 for placing the cabinet door 700, and the storage platform 200 is provided with a first positioning surface 210, and the surface of the first positioning surface 210 should be smooth. The positioning member 300 is slidably connected to the mounting base 100 through a sliding mechanism, so that the positioning member 300 can move from one side of the mounting base 100 to the other side, wherein the positioning member 300 is located above the first positioning surface 210, and the positioning member 300 is provided with a second positioning surface 310. When the cabinet door 700 and the handle 800 need to be installed, the first positioning surface 210 and the second positioning surface 310 are used to realize the positioning and limitation of the cabinet door 700. Among them, several first clamping assemblies 500 are arranged at intervals on one side of the mounting base 100, and the first clamping assemblies 500 include a first clamping block 510 that can move toward the second positioning surface 310. Several second clamping assemblies 600 are arranged at intervals on one side of the mounting base 100, and the second clamping assemblies 600 include a second clamping block 620 that can move toward the first positioning surface 210. In this embodiment, the number of the first clamping assemblies 500 and the second clamping assemblies 600 is preferably 5, which can be increased or decreased according to the actual length of the specific cabinet door 700, so that the handle 800 can fit the cabinet door 700 evenly and seamlessly.

[0032] When installing the cabinet door 700 and the handle 800, first adjust the positioning member 300 according to the width of the cabinet door 700 so that the distance between the second positioning surface 310 of the positioning member 300 and the first clamping block 510 is greater than the width of the cabinet door 700. After the adjustment is completed, fix the sliding mechanism, place the cabinet door 700 on the first positioning surface 210, push the cabinet door 700 to make one side of the cabinet door 700 fit the second positioning surface 310, and then place the handle 800 between the cabinet door 700 and the first clamping block 510. After completion, the first clamping assembly 500 and the second clamping assembly 600 are actuated to apply pressure to the vertical and horizontal surfaces of the handle 800 from the horizontal and vertical directions, such as Figure 2 and Figure 3 As shown, the docking side of the handle 800 is firmly attached to the docking side of the cabinet door 700. Compared with the previous method that a worker needs to press the handle 800 on the cabinet door 700 with one hand, or a worker presses another worker to screw, the mechanical structure realizes the pressing and fitting of the handle 800 and the cabinet door 700. One worker can quickly fix the handle 800 and the cabinet door 700 together by screws, and the mechanical pressing and fitting of the handle 800 and the cabinet door 700 can reduce the problem of unstable processing quality or uneven installation gap between the handle 800 and the cabinet door 700 caused by manual pressing and fitting. In addition, cabinet doors 700 of different specifications and sizes can all use this installation device to install the handle 800, which has wide applicability. Compared with the previous installation method of the handle 800, only one person can complete the batch installation of the cabinet door 700 and the handle 800, effectively shortening the production cycle.

[0033] In some embodiments, both ends of the positioning member 300 are provided with a sliding mechanism, and the sliding mechanism includes two sliding blocks 400, and the two sliding blocks 400 are both slidably connected to the mounting base 100. The two sliding blocks 400 are arranged in parallel, and the two sliding blocks 400 are movably connected through a connecting member, one of the sliding blocks 400 is fixedly connected to the positioning member 300, and the sliding blocks 400 fixedly connected to both ends of the positioning member 300 support the entire positioning member 300, so that the positioning member 300 is in a state of being mounted on the first positioning surface 210, and the positioning member 300 can slide from one side of the mounting base 100 to the other side. It should be noted that the two sides of the mounting base 100 are parallel, and the movement direction of the positioning member 300 is perpendicular to the side of the mounting base 100.

[0034] Specifically, a guide groove 110 is provided on the mounting base 100, and the guide groove 110 runs through both sides of the mounting base 100. The slider member 400 has a slide rail 420 that can cooperate with the guide groove 110, and each slide rail 420 corresponds to a guide groove 110. The guide grooves 110 are parallel to each other, and the extension direction of the guide groove 110 is perpendicular to the side of the mounting base 100, wherein the cross-section of the guide groove 110 is U-shaped, which facilitates the sliding of the slide rail 420 in the guide groove 110. The U-shaped guide groove 110 makes the contact between the slide rail 420 and the guide groove 110 a line or point contact, thereby reducing the contact area between the slide rail 420 and the guide groove 110, thereby reducing the friction between the slide rail 420 and the guide groove 110, so that the slide rail 420 slides more naturally in the guide groove 110.

[0035] In some embodiments, a through hole 410 for a connecting member to pass through is provided on a slider member 400 away from the end of the positioning member 300. The connecting member includes a clamping head and a stud which are connected to each other. The stud passes through the through hole 410 and is threadedly connected to another slider member 400. The diameter of the clamping head is larger than the diameter of the through hole 410. When the positioning member 300 is adjusted and the position of the positioning member 300 needs to be fixed, the clamping head is screwed to drive the stud and the slider member 400 to realize a threaded linear motion. Since the diameter of the clamping head is larger than the diameter of the through hole 410, the clamping head can press the slider member 400 away from the end of the positioning member 300 toward the slider member 400 fixedly connected to the end of the positioning member 300. The two slider members 400 on the same end of the positioning member 300 are close to each other, so that the two slider members 400 clamp the groove wall between the two guide grooves 110. The block 400 is pressed against the groove wall of the guide groove 110 under the action of the connecting member, increasing the friction force. Even if a lot of force is used to push the positioning member 300, it cannot be pushed away from the existing position, so that the position of the positioning member 300 is fixed. When the positioning member 300 needs to be adjusted, the connecting member is screwed so that the connection between the two ends of the positioning member 300 becomes a movable connection, and the restriction of the clamping head is lost. The slide rail 420 of the slider member 400 can slide naturally on the guide groove 110, which is convenient for adjusting the position of the positioning member 300. The connecting member is not shown in the drawings, but the connecting member of the embodiment of the present invention can be a bolt or a structural member similar to a bolt.

[0036] In this embodiment, the first clamping assembly 500 and the second clamping assembly 600 are arranged on the same side of the mounting base 100, and the first positioning surface 210 is perpendicular to the second positioning surface 310. Specifically, the first clamping assembly 500 includes a first cylinder, the movement direction of the cylinder shaft of the first cylinder is parallel to the first positioning surface 210, and the first clamping block 510 is arranged on the cylinder shaft of the first cylinder. The first clamping block 510 is driven by the first cylinder to move toward the second positioning surface 310, so that the first mounting surface 810 of the handle 800 can be pushed from the horizontal direction to the second mounting surface that fits the cabinet door 700. It should be noted that the second mounting surface is located on the side of the cabinet door 700.

[0037] In some other embodiments, the second clamping assembly 600 further includes a second cylinder and a connecting strip 610, the cylinder axis of the second cylinder is perpendicular to the first positioning surface 210, one end of the connecting strip 610 is fixedly connected to the cylinder axis of the second cylinder, and the second clamping block 620 is fixed to the other end of the connecting strip 610 extending above the first positioning surface 210. The second clamping block 620 is driven by the second cylinder to press downward from the vertical direction to push the third mounting surface 820 of the handle 800 to the fourth mounting surface pressed against the corresponding position of the cabinet door 700, and the interval arrangement of the plurality of first clamping assemblies 500 and the second clamping assemblies 600 enables the long-span handle 800 to be effectively and evenly fitted with the cabinet door 700. Among them, the first clamping block 510 and the second clamping block 620 are both made of high-strength rubber, which has a certain hardness, but will not scratch the surface of the handle 800 when the handle 800 is pressed, thereby effectively protecting the aesthetics of the handle 800.

[0038] In order to facilitate the simultaneous control of multiple first cylinders and multiple second cylinders, a main air circuit is provided on the mounting base 100, and a pressure gauge 130 and a ventilation switch 120 are provided on the main air circuit. The main air pipe is further divided into two bronchial pipes, one bronchial pipe supplies air to each first cylinder, and the other bronchial pipe supplies air to the second cylinders. In order to facilitate the simultaneous on and off control of multiple first cylinders and the simultaneous on and off control of multiple second cylinders, a first switch 140 for controlling the on and off of the bronchial air circuit is provided on the bronchial pipe supplying air to the first cylinders, and a second switch 150 for controlling the on and off of the bronchial air circuit is provided on the bronchial pipe supplying air to the second cylinders. When the cabinet door 700 and the handle 800 need to be installed, turn on the ventilation switch 120. When the air pressure display value of the barometer 130 reaches 1MPa and the cabinet door 700 and the handle 800 are placed, turn on the first switch 140 so that the first cylinder simultaneously drives the first clamping block 510 to push the handle 800 and the cabinet door 700 to fit together in the horizontal direction. Then turn on the second switch 150 so that each second cylinder simultaneously drives the second clamping block 620 to push the handle 800 and the cabinet door 700 to fit together in the vertical direction, thereby achieving uniform fitting of the handle 800 and the cabinet door 700 at all locations. After screwing, the installation quality of the handle 800 and the cabinet door 700 is better, effectively improving the product life.

[0039] The embodiment of the present invention further provides a method for installing a cabinet door 700 and a handle 800 using the above-mentioned cabinet door external handle installation device, which specifically includes the following steps:

[0040] The positioning member 300 is adjusted according to the width of different cabinet doors 700, so that the distance between the first positioning surface 210 and the first pressing block 510 is greater than the width of the cabinet door 700, so that the cabinet door 700 is conveniently placed in the first positioning surface 210 or taken out from the first positioning surface 210, and then the sliding mechanism is locked to ensure that the positioning member 300 will not be displaced when the cabinet door 700 and the handle 800 are fitted together. After completion, the cabinet door 700 is placed on the first positioning surface 210, and one side of the cabinet door 700 is close to the second positioning surface 310, and the other side of the cabinet door 700 is located under the second pressing block 620, and the handle 800 is removed from the installation base. The side of the table 100 is placed between the cabinet door 700 and the first clamping block 510, and the end of the handle 800 is aligned with the end of the cabinet door 700, and then the first installation surface 810 of the handle 800 is preliminarily fitted with the second installation surface of the cabinet door 700, and the third installation surface 820 of the handle 800 is preliminarily fitted with the fourth installation surface of the cabinet door 700. After completion, the first clamping assembly 500 and the second clamping assembly 600 are actuated to make the docking side of the handle 800 close to the docking side of the cabinet door 700, and then screws are manually screwed into the corresponding holes at the docking point of the handle 800 and the cabinet door 700 to complete the installation of the handle 800 and the cabinet door 700.

[0041] Among them, the action process of the first clamping assembly 500 and the second clamping assembly 600 includes: several first clamping assemblies 500 are first actuated simultaneously, so that the first clamping assemblies 500 push the first mounting surface 810 of the handle 800 to mate with the second mounting surface of the cabinet door 700, and then several second clamping assemblies 600 are actuated simultaneously, so that the third mounting surface 820 of the handle 800 and the fourth mounting surface of the cabinet door 700 are evenly fitted. The first clamping assembly 500 is actuated first, mainly to achieve positioning through the first mounting surface 810 of the handle 800 and the second mounting surface of the cabinet door 700, and then the second clamping assembly 600 is driven to actuate, in order to make the surfaces of the docking point between the handle 800 and the cabinet door 700 evenly fit.

[0042] Compared with the original manual installation which requires more than two persons to complete, the installation device and method of the present application only require one person to operate the cabinet door 700 and the handle 800 which are longer than two meters. The mechanical pressing method can reduce the labor cost investment of more than one person and improve the processing efficiency by about 30%. Compared with manual pressing, the mechanical pressing method can reduce the unstable processing quality caused by manual operation, such as the problem of uneven installation gap of the handle 800 caused by improper pressing, and can also effectively improve the assembly efficiency of the cabinet door 700 and the handle 800.

[0043] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
